【Abstract】 The thermodynamic equilibrum principle of the PTA oxidation reaction system was overall studied.A complete thermodynamic equilibrum data base was established according to the system.The published thermodynamic equilibrum data related to the system was concluded.Part of the phase equilibrum data were determined by the experiment.The interaction parameters among each mass were obtained by the regression of the experiment data.The raised thermodynamic model and parameters tallied with the literature data,experiment data and on-the-spot data better.The model and parameters provided powerful methods for the thermodynamic equilibrium calculation of PX oxidation process.更多还原
